RELATED APPLICATIONS

This application is a continuation application of U.S. Ser. No.15/750,811 filed Feb. 6, 2018, which is a national phase application ofPCT Application No. PCT/US16/45849, filed Aug. 5, 2016; which claims thebenefit of provisional application U.S. Ser. No. 62/202,578, filed Aug.7, 2015, the contents of each of which are herein incorporated byreference in its entirety.

FIELD OF THE DISCLOSURE

The disclosure is directed to fields of small molecules, medicine,biomarkers, inflammation, and allergy. Specifically, the disclosure isdirected to the use of a mast cell stabilizer or a compositioncomprising a mast cell stabilizer for the treatment of a mast cellrelated disorder by systemic administration of the mast cell stabilizer.

BACKGROUND

Mast cells play a key role in the inflammatory process. They are foundin the perivascular spaces of most tissues and contain pro-inflammatoryand vasoactive mediators, such as serine proteases, tryptase, histamine,serotonin, proteoglycans, thromboxane, prostaglandin D2, leukotriene C4,platelet-activating factor, and eosinophil chemotactic factor. Whenactivated, mast cells rapidly release granules and various hormonemediators into the interstitium, a process referred to as degranulation.Degranulation of mast cells can be caused by physical or chemicalinjury, crosslinking of immunoglobulin G receptors, or by activatedcomplement proteins.

Systemic mast cell related disorders may result from excessiveproliferation of mast cells or abnormal release of pro-inflammatory andvasoactive mediators. Symptoms of systemic mast cell related disordersinclude pruritus, flushing, nausea, vomiting, diarrhea, headaches,abdominal pain, vascular instability, urticaria, itching, andanaphylaxis. Accumulation of mast cells in the skin, gastrointestinaltract, bone marrow, liver, spleen, and lymph nodes may result in aparticular systemic mast cell related disorder, systemic mastocytosis,or mastocytosis.

The utility of mast cell stabilizers in the treatment of systemic mastcell related disorders, such as mastocytosis, has been limited. Forexample, cromolyn sodium (also known as disodium cromoglycate or DSCG)was first approved in 1973 and is widely considered safe, but it hasfound limited utility because the amount of the compound that can bedelivered systemically is inadequate. An oral solution of cromolynsodium is available for the treatment of systemic mast cell relateddisorders, such as mastocytosis (Gastrocrom®). However, the oralsolution is only modestly effective for treating localizedgastrointestinal symptoms, and it is not effective for the treatment ofsystemic symptoms because of the low oral bioavailability of cromolynsodium (less than 1%).

Efforts have been made to increase the oral bioavailability of cromolynsodium in order to provide systemically effective amounts for thetreatment of systemic mast cell related disorders, but these effortshave not yielded products that achieve significantly higher oralbioavailability of cromolyn sodium in a practical, safe, andwell-tolerated manner. Accordingly, a need exists for methods ofdelivering mast cell stabilizers, such as cromolyn sodium, that achievehigher systemic levels than previously considered or thought possible,in a practical, safe, and well-tolerated manner, in order tosignificantly improve clinical outcomes for patients suffering fromsystemic mast cell related disorders.

DETAILED DESCRIPTION

Unless defined otherwise, all technical and scientific terms used hereinhave the same meaning as commonly understood by one of skill in the artto which the inventions described herein belong. All publications,patents, and patent applications mentioned in this specification arehereby incorporated by reference to the same extent as if eachindividual publication, patent, or patent application was specificallyand individually indicated to be incorporated by reference.

Definition of Terms

As used herein, the term “about” is used synonymously with the term“approximately.” Illustratively, the use of the term “about” with regardto a certain therapeutically effective pharmaceutical dose indicatesthat values in a range spanning a cited value, e.g., plus or minus up to10% of a cited value, are also effective and safe.

As used herein, the terms “comprising,” “including,” “such as,” and “forexample” (or “e.g.”) are used in their open, non-limiting sense.

As used herein, the phrase “consisting essentially of” is a transitionalphrase used in a claim to indicate that the following list ofingredients, parts or process steps must be present in the claimedcomposition, machine or process, but that the claim is open to unlistedingredients, parts or process steps that do not materially affect thebasic and novel properties of the invention.

“Nominal dose,” as used herein, refers to the loaded dose, which is theamount of mast cell stabilizer in an inhalation device prior toadministration to the patient. The volume of solution containing thenominal dose is referred to as the “fill volume.”

“AUC_(last)” as used herein refers to the area under the curve from timezero to time of last measurable concentration of active pharmaceuticalingredient (API).

“AUC_(last) ^(HEN)” as used herein refers to the area under a bloodplasma concentration curve up to the last time point for the nominaldose of active pharmaceutical ingredient (API) administered with a highefficiency nebulizer.

“AUC_(last) ^(Conv)” as used herein refers to the area under a bloodplasma concentration curve up to the last time point for a nominal doseof active pharmaceutical ingredient (API) administered with aconventional inhalation device.

“AUC_((0-∞))” as used herein refers to the total area under a bloodplasma concentration curve for an active pharmaceutical ingredient(API).

“AUC_((0-∞)) ^(CONV)” as used herein refers to the total area under ablood plasma concentration curve for a nominal dose of activepharmaceutical ingredient (API) administered with a conventionalinhalation device.

AUC_((0-∞)) can be determined by methods known to those of skill in theart. For example, the AUC_((0-∞)) of an API can be determined bycollecting blood samples from a subject at various time points afteradministration of an API to the subject, separating plasma from theblood samples, extracting the API from the separated plasma samples,e.g., by solid-phase extraction, quantifying the amount of the APIextracted from each sample of separated plasma, e.g., by liquidchromatography-tandem mass spectrometry (LC-MS/MS), plotting theconcentration of API in each sample versus the time of collection afteradministration, and calculating the area under the curve.

“Substantially the same nominal dose” as used herein means that a firstnominal dose of an active pharmaceutical ingredient (API) containsapproximately the same number of millimoles of the mast cell stabilizeras a second nominal dose of the mast cell stabilizer.

“Bioavailability” as used herein refers to the amount of unchanged APIthat reaches the systemic circulation, expressed as a percentage of thedosage of the API that is administered to a subject. By definition, thebioavailability of an intravenous solution containing the activepharmaceutical ingredient (API) is 100%. The bioavailability of an APIcan be determined by methods known to those of skill in the art. Forexample, the bioavailability of an API can be determined by collectingurine samples from a subject at various time points followingadministration of the API to the subject, extracting the API from theurine samples, e.g., by solid-phase extraction, quantifying the amountof the API in each urine sample, adjusting the amount of API collectedfrom the urine by a factor based on the amount of API reaching systemiccirculation that is excreted in the urine, and calculating thepercentage of the API administered to the subject that reaches thesystemic circulation of the subject. In a specific embodiment, thebioavailability of cromolyn sodium can be determined as described inWalker et al., 24 J. Pharm. Pharmacol. 525-31 (1972). In the case ofcromolyn sodium, the amount of the compound isolated from the urine ismultiplied by two to calculate the total amount reaching systemiccirculation after administration because the compound is known to beexcreted unmetabolized in equal parts in the urine and feces, i.e.,approximately 50% of the amount of cromolyn sodium that reaches systemiccirculation is excreted in the urine and approximately 50% of the amountof cromolyn sodium that reaches systemic circulation is excreted in thefeces.

“Enhanced lung deposition” as used herein refers to an increase in drugdeposition (deposited lung dose) arising out of, for example, improvedefficiency of drug delivery.

“Deposited dose” or “deposited lung dose” is the amount of mast cellstabilizer deposited in the lung. The deposited dose or deposited lungdose may be expressed in absolute terms, for example in mg or μg of APIdeposited in the lungs. The deposited lung dose may also be expressed inrelative terms, for example calculating the amount of API deposited as apercentage of the nominal dose.

“C_(max)” as used herein refers to the maximum plasma concentration foran active pharmaceutical ingredient (API).

“C_(max) ^(CONV)” as used herein refers to the maximum blood plasmaconcentration for a nominal dose of the active pharmaceutical ingredient(API) administered with a conventional inhalation device.

C_(max) can be determined by methods known to those of skill in the art.For example, the C_(max) of an API can be determined by collecting bloodsamples from a subject at various time points after administration of anAPI to the subject, separating plasma from the blood samples, extractingthe API from the separated plasma samples, e.g., by solid-phaseextraction, quantifying the amount of the API extracted from each sampleof separated plasma, e.g., by LC-MS/MS, plotting the concentration ofAPI in each sample versus the time of collection after administration,and identifying the peak concentration of the API on the curve.

“Enhanced pharmacokinetic profile” means an improvement in somepharmacokinetic parameter. Pharmacokinetic parameters that may beimproved include AUC (0-4 or 0-6 or 0-8 h), AUC_(last), AUC_((0-∞)),T_(max), T_(1/2), and C_(max). In some embodiments, the enhancedpharmacokinetic profile may be measured quantitatively by comparing apharmacokinetic parameter obtained for a nominal dose of an activepharmaceutical ingredient (API) administered by one route ofadministration, such as an inhalation device (e.g., a high efficiencynebulizer) with the same pharmacokinetic parameter obtained with thesame nominal dose of active pharmaceutical ingredient (API) administeredby a different route of administration, such as a different type ofinhalation device or an oral formulation (e.g., oral tablet, oralcapsule, or oral solution).

“Blood plasma concentration” refers to the concentration of an activepharmaceutical ingredient (API) in the plasma component of blood of asubject or patient population.

“Patient” or “subject” refers to the animal (especially mammal) or humanbeing treated.

A “subject group” or “patient group” has a sufficient number of subjectsor patients to provide a statistically significant average measurementof the relevant pharmacokinetic parameter. All members of the “subjectgroup” or “patient group” have pharmacokinetic parameters for the mastcell stabilizers that fall within statistically normal ranges (i.e.,there are no outliers), and no member is included on the basis ofnon-standard or unusual measurements.

“Nebulizer,” as used herein, refers to a device that turns medications,compositions, formulations, suspensions, and mixtures, etc. into a fineaerosol mist for delivery to the lungs.

“Drug absorption” or simply “absorption” typically refers to the processof movement of drug from site of delivery of a drug across a barrierinto a blood vessel or the site of action, e.g., a drug being absorbedvia the pulmonary capillary beds of the alveoli into the systemiccirculation.

“T_(max)” as used herein refers to the amount of time necessary for anactive pharmaceutical ingredient (API) to attain maximum blood plasmaconcentration.

“T_(max) ^(HEN)” as used herein refers to the amount of time necessaryfor a nominal dose of an active pharmaceutical ingredient (API) toattain maximum blood plasma concentration after administration with ahigh efficiency nebulizer.

“T_(max) ^(CONV)” as used herein refers to the amount of time necessaryfor a nominal dose of an active pharmaceutical ingredient (API) toattain maximum blood plasma concentration after administration with aconventional inhalation device.

The term “treat” and its grammatical variants (e.g., “to treat,”“treating,” and “treatment”) refer to administration of an activepharmaceutical ingredient to a patient with the purpose of amelioratingor reducing the incidence of one or more symptoms of a condition ordisease state in the patient. Such symptoms may be chronic or acute; andsuch amelioration may be partial or complete. In the present context,treatment entails administering a mast cell stabilizer to a patient viaany route of administration disclosed herein.

As used herein, the term “high concentration” refers to a concentrationgreater than 1% by weight. For example, in a specific embodiment, a“high concentration” formulation of cromolyn sodium comprises cromolynsodium at a concentration of greater than 1% by weight.

As used herein, the term “hypotonic” refers to a formulation that has atonicity less than 295 mOsm/kg.

The term “prophylaxis” refers to administration of an activepharmaceutical ingredient to a patient with the purpose of reducing theoccurrence or recurrence of one or more acute symptoms associated with adisease state or a condition in the patient. In the present context,prophylaxis entails administering a mast cell stabilizer to a patientvia any route of administration disclosed herein. Thus, prophylaxisincludes reduction in the occurrence or recurrence rate of a systemicmast cell related disorder. However, prophylaxis is not intended toinclude complete prevention of onset of a disease state or a conditionin a patient who has not previously been identified as suffering fromthe disease or the condition.

As used herein, a “systemically effective amount” is an amount of mastcell stabilizer in the body of a patient as a whole that is effectivefor the treatment or prophylaxis of a systemic mast cell relateddisorder. A “systemically effective amount” may be expressed, forexample, as the mass of a mast cell stabilizer, or concentration of amast cell stabilizer, in a patient's plasma. A “systemically effectiveamount” may differ depending on the specific mast cell stabilizer andthe specific systemic mast cell related disorder.

Mast cellstabilizers, including cromolyn and pharmaceutically-acceptable salts,prodrugs, and adducts thereof, may be prepared by methods known in theart.

In some embodiments, mast cell stabilizers described herein may beprepared as prodrugs. A “prodrug” refers to an agent that is convertedinto the parent drug in vivo. The prodrug can be designed to alter themetabolic stability or the transport characteristics of a drug, to maskside effects or toxicity, to improve the flavor of a drug, or to alterother characteristics or properties of a drug. In some embodiments, theprodrug has improved bioavailability relative to the parent drug. Insome embodiments, the prodrug has improved solubility in pharmaceuticalcompositions over the parent drug. In some embodiments, prodrugs may bedesigned as reversible drug derivatives, for use as modifiers to enhancedrug transport to site-specific tissues. In some embodiments, a prodrugof a mast cell stabilizer is an ester of the mast cell stabilizer, whichis hydrolyzed to the carboxylic acid, the parent mast cell stabilizer.In some embodiments, a prodrug comprises a short peptide (polyaminoacid)bonded to an acid group, wherein the peptide is metabolized in vivo toreveal the parent drug. In certain embodiments, upon in vivoadministration, a prodrug is chemically converted to the biologically,pharmaceutically or therapeutically active form of the mast cellstabilizer. In certain embodiments, a prodrug is enzymaticallymetabolized by one or more steps or processes to the parent mast cellstabilizer. In certain embodiments, the mast cell stabilizer is aprodrug of cromolyn. In a specific embodiment, the prodrug of cromolynis cromoglicate lisetil.

To produce a prodrug, a pharmaceutically active mast cell stabilizercompound is modified such that the active compound will be regeneratedupon in vivo administration. In some embodiments, prodrugs of mast cellstabilizers are designed by virtue of knowledge of pharmacodynamicprocesses and drug metabolism in vivo. See, e.g., Nogrady (1985)Medicinal Chemistry A Biochemical Approach, Oxford University Press, NewYork, pages 388-392; Silverman (1992), The Organic Chemistry of DrugDesign and Drug Action, Academic Press, Inc., San Diego, pages 352-401,Saurnier et al., (1994), Bioorganic and Medicinal Chemistry Letters,Vol. 4, p. 1985; Rooseboom et al., Pharmacological Reviews, 56:53-102,2004; Miller et al., J. Med. Chem. Vol. 46, no. 24, 5097-5116, 2003;Aesop Cho, “Recent Advances in Oral Prodrug Discovery”, Annual Reportsin Medicinal Chemistry, Vol. 41, 395-407, 2006.

In some embodiments, mast cell stabilizers described herein includeisotopically-labeled compounds, which are identical to those recitedherein, but for the fact that one or more atoms are replaced by an atomhaving an atomic mass or mass number different from the atomic mass ormass number usually found in nature. Examples of isotopes that can beincorporated into the present compounds include isotopes of hydrogen,carbon, nitrogen, oxygen, fluorine and chlorine, such as, for example,²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F, ³⁶Cl, respectively. Certainisotopically labeled compounds described herein, for example those withisotopes such as deuterium, i.e., ²H, can afford certain therapeuticadvantages resulting from greater metabolic stability, such as, forexample, increased in vivo half-life or reduced dosage requirements. Incertain embodiments, the mast cell stabilizer is isotopically labeledcromolyn, or a pharmaceutically acceptable salt thereof, such ascromolyn sodium. In some embodiments, the mast cell stabilizer isdeuterium-labeled cromolyn sodium.

In some embodiments, mast cell stabilizers described herein may bePEGylated, wherein one or more polyethylene glycol (PEG) polymers arecovalently attached to the mast cell stabilizers. In some embodiments,pegylated mast cell stabilizers increase the half-life of the mast cellstabilizers in the body. In some embodiments, pegylation of the mastcell stabilizers increases the hydrodynamic size of the mast cellstabilizers and reduces their renal clearance. In some embodiments,pegylation of the mast cell stabilizers increases the solubility of themast cell stabilizers. In some embodiments, pegylation of the mast cellstabilizers protects the mast cell stabilizers from proteolyticdegradation.

Solid Oral Formulations

In some embodiments, the solid dosage forms disclosed herein may be inthe form of a tablet, (including a suspension tablet, a fast-melttablet, a bite-disintegration tablet, a rapid-disintegration tablet, aneffervescent tablet, an osmotic pump tablet, or a caplet), a pill, apowder (including a sterile packaged powder, a dispensable powder, or aneffervescent powder), a capsule (including both soft or hard capsules,e.g., capsules made from animal-derived gelatin or plant-derived HPMC,or “sprinkle capsules”), solid dispersion, solid solution, bioerodibledosage form, controlled release formulations, pulsatile release dosageforms, multiparticulate dosage forms, pellets, or granules. In someembodiments, systemically effective amounts of mast cell stabilizers areachieved with solid oral formulations by including one or more ofpermeation enhancers and enteric coatings in the solid oralformulations. In some embodiments, enteric coatings regulate thedelivery a mast cell stabilizer during its passage through the stomachand intestine.

The pharmaceutical solid dosage forms described herein can include amast cell stabilizer and one or more pharmaceutically inactiveingredients such as a compatible carrier, binder, filling agent,suspending agent, flavoring agent, sweetening agent, disintegratingagent, dispersing agent, surfactant, lubricant, colorant, diluent,solubilizer, moistening agent, plasticizer, stabilizer, penetrationenhancer, wetting agent, anti-foaming agent, antioxidant, preservative,or one or more combination thereof.

In some embodiments, solid dosage forms, e.g., tablets, effervescenttablets, and capsules, are prepared by mixing particles of a mast cellstabilizer with one or more pharmaceutical excipients to form a bulkblend composition. When referring to these bulk blend compositions ashomogeneous, it is meant that the particles of the mast cell stabilizerare dispersed evenly throughout the composition so that the compositionmay be readily subdivided into equally effective unit dosage forms, suchas tablets, pills, and capsules. The individual unit dosages may alsoinclude film coatings, which disintegrate upon oral ingestion or uponcontact with diluent. These formulations can be manufactured byconventional pharmacological techniques, e.g., one or a combination of:(1) dry mixing, (2) direct compression, (3) milling, (4) dry ornon-aqueous granulation, (5) wet granulation, and (6) fusion. See, e.g.,Lachman et al., The Theory and Practice of Industrial Pharmacy (1986).Other methods include, e.g., spray drying, pan coating, meltgranulation, granulation, fluidized bed spray drying or coating (e.g.,wurster coating), tangential coating, top spraying, tableting, extrudingand the like.

Pharmaceutical preparations for oral use can be obtained by mixing oneor more solid excipient with one or more mast cell stabilizers,optionally grinding the resulting mixture, and processing the mixture ofgranules, after adding suitable auxiliaries, if desired, to obtaintablets or dragee cores. In some embodiments, dragee cores are providedwith suitable coatings. For this purpose, concentrated sugar solutionsmay be used, which may optionally contain gum arabic, talc,polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titaniumdioxide, lacquer solutions, and suitable organic solvents or solventmixtures. Dyestuffs or pigments may be added to the tablets or drageecoatings for identification or to characterize different combinations ofactive compound doses.

In other embodiments, a powder including a mast cell stabilizer may beformulated to include one or more pharmaceutical excipients and flavors.Such a powder may be prepared, for example, by mixing the formulationand optional pharmaceutical excipients to form a bulk blend composition.Additional embodiments also include a suspending agent and/or a wettingagent. This bulk blend is uniformly subdivided into unit dosagepackaging or multi-dosage packaging units.

Compressed tablets are solid dosage forms prepared by compacting thebulk blend of the formulations described above. In some embodiments, thecompressed tablets will include a film surrounding the final compressedtablet. In some embodiments, the film coating can provide a delayedrelease of the mast cell stabilizer from the formulation. In otherembodiments, the film coating aids in patient compliance. Film coatingssuch as Opadry® typically range from about 1% to about 3% of the tabletweight. In other embodiments, the compressed tablets include one or morepharmaceutical excipients.

A capsule may be prepared, for example, by placing the bulk blend of theformulation of the mast cell stabilizer inside of a capsule. In someembodiments, the formulations (non-aqueous suspensions and solutions)are placed in a soft gelatin capsule. In other embodiments, theformulations are placed in standard gelatin capsules or non-gelatincapsules such as capsules comprising HPMC. In other embodiments, theformulation is placed in a sprinkle capsule, wherein the capsule may beswallowed whole or the capsule may be opened and the contents sprinkledon food prior to eating. In some embodiments, the therapeutic dose issplit into multiple (e.g., two, three, or four) capsules. In someembodiments, the entire dose of the formulation is delivered in acapsule form.

In some embodiments, dosage forms may include microencapsulatedformulations. Materials useful for the microencapsulation includematerials compatible with mast cell stabilizers, which sufficientlyisolate mast cell stabilizers from other non-compatible excipients.Materials compatible with mast cell stabilizers are those that delay therelease of the mast cell stabilizers in vivo. Exemplarymicroencapsulation materials useful for delaying the release of theformulations include, but are not limited to, hydroxypropyl celluloseethers (HPC) such as Klucel® or Nisso HPC, low-substituted hydroxypropylcellulose ethers (L-HPC), hydroxypropyl methyl cellulose ethers (HPMC)such as Seppifilm-LC, Pharmacoat®, Metolose SR, Methocel®-E, Opadry YS,PrimaFlo, Benecel MP824, and Benecel MP843, methylcellulose polymerssuch as Methocel®-A, hydroxypropylmethylcellulose acetate stearate Aqoat(HF-LS, HF-LG, HF-MS) and Metolose®, Ethylcelluloses (EC) and mixturesthereof such as E461, Ethocel®, Aqualon®-EC, Surelease®, Polyvinylalcohol (PVA) such as Opadry AMB, hydroxyethylcelluloses such asNatrosol®, carboxymethylcelluloses and salts of carboxymethylcelluloses(CMC) such as Aqualon®-CMC, polyvinyl alcohol and polyethylene glycolco-polymers such as Kollicoat IR®, monoglycerides (Myverol),triglycerides (KLX), polyethylene glycols, modified food starch, acrylicpolymers and mixtures of acrylic polymers with cellulose ethers such asEudragit® EPO, Eudragit® L30D-55, Eudragit® FS 30D Eudragit® L100-55,Eudragit® L100, Eudragit® 5100, Eudragit® RD100, Eudragit® E100,Eudragit® L12.5, Eudragit® 512.5, Eudragit® NE30D, and Eudragit® NE 40D,cellulose acetate phthalate, sepifilms such as mixtures of HPMC andstearic acid, cyclodextrins, and mixtures of these materials. In someembodiments, plasticizers such as polyethylene glycols, e.g., PEG 300,PEG 400, PEG 600, PEG 1450, PEG 3350, and PEG 800, stearic acid,propylene glycol, oleic acid, and triacetin are incorporated into themicroencapsulation material.

Such known methods include,e.g., spray drying processes, spinning disk-solvent processes, hot meltprocesses, spray chilling methods, fluidized bed, electrostaticdeposition, centrifugal extrusion, rotational suspension separation,polymerization at liquid-gas or solid-gas interface, pressure extrusion,or spraying solvent extraction bath. In addition to these, severalchemical techniques, e.g., complex coacervation, solvent evaporation,polymer-polymer incompatibility, interfacial polymerization in liquidmedia, in situ polymerization, in-liquid drying, and desolvation inliquid media could also be used. Furthermore, other methods such asroller compaction, extrusion/spheronization, coacervation, ornanoparticle coating may also be used.

In other embodiments, the formulations described herein are soliddispersions. Methods of producing such solid dispersions are known inthe art and include, but are not limited to, for example, U.S. Pat. Nos.4,343,789, 5,340,591, 5,456,923, 5,700,485, and 5,723,269, as well asU.S. Pub. Appl. 2004/0013734, each of which is specifically incorporatedby reference herein. In still other embodiments, the formulationsdescribed herein are solid solutions. Solid solutions incorporate asubstance together with the mast cell stabilizer and other excipientssuch that heating the mixture results in dissolution of the drug and theresulting composition is then cooled to provide a solid blend which canbe further formulated or directly added to a capsule or compressed intoa tablet. Methods of producing such solid solutions are known in the artand include, but are not limited to, for example, U.S. Pat. Nos.4,151,273, 5,281,420, and 6,083,518, each of which is specificallyincorporated by reference herein.

In other embodiments, formulations described herein include a matrixbased dosage form. In a matrix-based dosage form described herein, atleast one mast cell stabilizer and optional pharmaceutically acceptableexcipient(s) are dispersed within a polymeric matrix, which typicallycomprises one or more water-soluble polymers and/or one or morewater-insoluble polymers. The drug can be released from the dosage formby diffusion and/or erosion. Suitable water-soluble polymers include,but are not limited to, polyvinyl alcohol, polyvinylpyrrolidone,methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose,or polyethylene glycol, and/or mixtures thereof. Suitablewater-insoluble polymers also include, but are not limited to,ethylcellulose, cellulose acetate, cellulose propionate, celluloseacetate propionate, cellulose acetate butyrate, cellulose acetatephthalate, cellulose triacetate, poly (methyl methacrylate), poly (ethylmethacrylate), poly (butyl methacrylate), poly (isobutyl methacrylate),and poly (hexyl methacrylate), poly (isodecyl methacrylate), poly(lauryl methacrylate), poly (phenylmethacrylate), poly (methylacrylate), poly (isopropyl acrylate), poly (isobutyl acrylate), poly(octadecyl acrylate), poly (ethylene), poly (ethylene) low density, poly(ethylene) high density, poly (ethylene oxide), poly (ethyleneterephthalate), poly (vinyl isobutyl ether), poly (vinyl acetate), poly(vinyl chloride) or polyurethane, an d/or mixtures thereof. Suitablepharmaceutically acceptable excipients include, but are not limited to,carriers, such as sodium citrate and dicalcium phosphate; fillers orextenders, such as stearates, silicas, gypsum, starches, lactose,sucrose, glucose, mannitol, talc, and silicic acid; binders, such ashydroxypropyl methylcellulose, hydroxymethyl-cellulose, alginates,gelatin, polyvinyl pyrrolidone, sucrose, and acacia; humectants, such asglycerol; disintegrating agents, such as agar, calcium carbonate, potatoand tapioca starch, alginic acid, certain silicates, EXPLOTAB,crospovidone, and sodium carbonate; solution retarding agents, such asparaffin; absorption accelerators, such as quaternary ammoniumcompounds; wetting agents, such as cetyl alcohol and glycerolmonostearate; absorbents, such as kaolin and bentonite clay; lubricants,such as talc, calcium stearate, magnesium stearate, solid polyethyleneglycols, and sodium lauryl sulfate; stabilizers, such as fumaric acid;coloring agents; buffering agents; dispersing agents; preservatives;organic acids; and organic bases. The aforementioned excipients aregiven as examples only and are not meant to include all possiblechoices. Additionally, many excipients can have more than one role orfunction, or can be classified in more than one group; theclassifications are descriptive only, and are not intended to limit anyuse of a particular excipient.

Matrix formulations of the present invention can be prepared by using,for example, direct compression or wet granulation. A functional coatingcan then be applied. Additionally, a barrier or sealant coat can beapplied over a matrix tablet core prior to application of a functionalcoating. The barrier or sealant coat can serve the purpose of separatingan active ingredient from a functional coating, which can interact withthe active ingredient, or it can prevent moisture from contacting theactive ingredient.

In some embodiments, the modified-release formulations described hereinare provided as osmotic pump dosage forms. In an osmotic pump dosageform, a core containing at least one mast cell stabilizer and optionallyat least one osmotic excipient is typically encased by a selectivelypermeable membrane having at least one orifice. The selectivelypermeable membrane is generally permeable to water, but impermeable tothe drug. When the system is exposed to body fluids, water penetratesthrough the selectively permeable membrane into the core containing thedrug and optional osmotic excipients. The osmotic pressure increaseswithin the dosage form. Consequently, the drug is released through theorifice(s) in an attempt to equalize the osmotic pressure across theselectively permeable membrane.

In more complex pumps, the dosage form can contain two internalcompartments in the core. The first compartment contains the drug andthe second compartment can contain a polymer, which swells on contactwith aqueous fluid. After ingestion, this polymer swells into thedrug-containing compartment, diminishing the volume occupied by thedrug, thereby forcing the drug from the device at a controlled rate overan extended period of time. Such dosage forms are often used when a zeroorder release profile is desired. Suitable swellable polymers typicallyinteract with water and/or aqueous biological fluids, which causes themto swell or expand to an equilibrium state. Acceptable polymers exhibitthe ability to swell in water and/or aqueous biological fluids,retaining a significant portion of such imbibed fluids within theirpolymeric structure, so as to increase the hydrostatic pressure withinthe dosage form. The polymers can swell or expand to a very high degree,usually exhibiting a 2- to 50-fold volume increase. The polymers can benon-cross-linked or cross-linked. In some embodiments, the swellablepolymers are hydrophilic polymers.

In some embodiments, mast cell stabilizers can be provided in amultiparticulate membrane-modified formulation. Membrane-modifiedformulations can be made by preparing a rapid release core, which can bea monolithic (e.g., tablet) or multi-unit (e.g., pellet) type, andcoating the core with a membrane. The membrane-modified core can then befurther coated with a functional coating. In between themembrane-modified core and functional coating, a barrier or sealant canbe applied. The mast cell stabilizer can be formed into an active coreby applying the compound to a nonpareil seed. The at least one mast cellstabilizer can be applied with or without additional excipients onto theinert cores, and can be sprayed from solution or suspension using afluidized bed coater (e.g., Wurster coating) or pan coating system.Alternatively, a mast cell stabilizer can be applied as a powder ontothe inert cores using a binder to bind the mast cell stabilizer onto thecores. Active cores can also be formed by extrusion of the core withsuitable plasticizers and any other processing aids as necessary.

The pharmaceutical solid oral dosage forms described herein can befurther formulated to provide a controlled release of the mast cellstabilizer. Controlled release refers to the release of the mast cellstabilizer from a dosage form in which it is incorporated according to adesired profile over an extended period of time. Controlled releaseprofiles include, for example, sustained release, prolonged release,pulsatile release, and delayed release profiles. In contrast toimmediate release compositions, controlled release compositions allowdelivery of an agent to a subject over an extended period of timeaccording to a predetermined profile. Such release rates can providetherapeutically effective levels of agent for an extended period of timeand thereby provide a longer period of pharmacologic response whileminimizing side effects as compared to conventional rapid release dosageforms. Such longer periods of response provide for many benefits thatare not achieved with the corresponding short acting, immediate releasepreparations.

In some embodiments, the solid dosage forms described herein can beformulated as enteric coated delayed release oral dosage forms, i.e., asan oral dosage form of a pharmaceutical composition as described hereinwhich utilizes an enteric coating to affect release in the smallintestine of the gastrointestinal tract. The enteric coated dosage formmay be a compressed or molded or extruded tablet/mold (coated oruncoated) containing granules, powder, pellets, beads or particles ofthe active ingredient and/or other composition components, which arethemselves coated or uncoated. The enteric coated oral dosage form mayalso be a capsule (coated or uncoated) containing pellets, beads orgranules of the solid carrier or the composition, which are themselvescoated or uncoated.

The term “delayed release” as used herein refers to the delivery so thatthe release can be accomplished at some generally predictable locationin the intestinal tract more distal to that which would have beenaccomplished if there had been no delayed release alterations. In someembodiments the method for delay of release is coating. Any coatingsshould be applied to a sufficient thickness such that the entire coatingdoes not dissolve in the gastrointestinal fluids at pH below about 5,but does dissolve at pH about 5 and above. It is expected that anyanionic polymer exhibiting a pH-dependent solubility profile can be usedas an enteric coating in the methods and compositions described hereinto achieve delivery to the lower gastrointestinal tract. In someembodiments the polymers described herein are anionic carboxylicpolymers. In other embodiments, the polymers and compatible mixturesthereof, and some of their properties, include, but are not limited toshellac acrylic polymers, cellulose derivatives, and poly vinyl acetatephthalate (PVAP).

Conventional coating techniques such as spray or pan coating areemployed to apply coatings. The coating thickness must be sufficient toensure that the oral dosage form remains intact until the desired siteof topical delivery in the intestinal tract is reached.

Intranasal Formulations

Intranasal formulations are known in the art and are described in, forexample, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452, each ofwhich is specifically incorporated by reference herein. The choice ofsuitable carriers is highly dependent upon the exact nature of the nasaldosage form desired, e.g., solutions, suspensions, ointments, or gels.Nasal dosage forms generally contain large amounts of water in additionto the active ingredient. Minor amounts of other ingredients such as pHadjusters, emulsifiers or dispersing agents, viscosity enhancing agents,preservatives, surfactants, gelling agents, or buffering and otherstabilizing and solubilizing agents may also be present. In someembodiments, the nasal dosage form is isotonic with nasal secretions. Insome embodiments a nasal dosage form is formulated to achieve sustaineddelivery. Examples of sustained delivery nasal dosage forms include, butare not limited to, dosage forms that include mucoadhesive agents suchas microcrystalline cellulose. In some embodiments, systemicallyeffective amounts of mast cell stabilizers are achieved with intranasalformulations by one or more of optimizing the droplet or particle sizeand including permeation enhancers in the intranasal formulation.

Buccal Formulations

Buccal formulations that include mast cell stabilizers may beadministered using a variety of formulations known in the art. Forexample, such formulations include, but are not limited to, thosedescribed in U.S. Pat. Nos. 4,229,447, 4,596,795, 4,755,386, and5,739,136, each of which is specifically incorporated by referenceherein. In addition, the buccal dosage forms can further include abioerodible (hydrolysable) polymeric carrier that also serves to adherethe dosage form to the buccal mucosa. The buccal dosage form isfabricated so as to erode gradually over a predetermined time period,wherein the delivery of the mast cell stabilizer is provided essentiallythroughout. Buccal drug delivery, as will be appreciated by thoseskilled in the art, avoids the disadvantages encountered with oral drugadministration, e.g., slow absorption, degradation of the active agentby fluids present in the gastrointestinal tract and/or first-passinactivation in the liver. With regard to the bioerodible (hydrolysable)polymeric carrier, it will be appreciated that virtually any suchcarrier can be used, so long as the desired drug release profile is notcompromised, and the carrier is compatible with the mast cell stabilizerand any other components that may be present in the buccal dosage unit.Generally, the polymeric carrier comprises hydrophilic (water-solubleand water-swellable) polymers that adhere to the wet surface of thebuccal mucosa. Examples of polymeric carriers useful herein includeacrylic acid polymers, e.g., those known as “carbomers” (Carbopol®,which may be obtained from B.F. Goodrich, is one such polymer). Othercomponents may also be incorporated into the buccal dosage formsdescribed herein include, but are not limited to, disintegrants,diluents, binders, lubricants, flavoring, colorants, preservatives, andthe like. In some embodiments, systemically effective amounts of mastcell stabilizers are achieved with buccal formulations by one or more ofoptimizing the erosion time of the formulation and by includingpermeation enhancers in the buccal formulations.

Transdermal Formulations

Transdermal formulations described herein may be administered using avariety of devices which have been described in the art. For example,such devices include, but are not limited to, those described in U.S.Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683, 3,742,951,3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073, 3,996,934,4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211, 4,230,105,4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280, 5,869,090,6,923,983, 6,929,801 and 6,946,144, each of which is specificallyincorporated by reference in its entirety herein.

Transdermal dosage forms for use in the methods disclosed herein mayincorporate certain pharmaceutically acceptable excipients which areconventional in the art. In one embodiment, the transdermal formulationsinclude at least three components: (1) a formulation of a mast cellstabilizer; (2) a penetration enhancer; and (3) an aqueous adjuvant. Inaddition, transdermal formulations can include additional componentssuch as, but not limited to, gelling agents, creams and ointment bases,and the like. In some embodiments, the transdermal formulation canfurther include a woven or non-woven backing material to enhanceabsorption and prevent the removal of the transdermal formulation fromthe skin. In other embodiments, the transdermal formulations describedherein can maintain a saturated or supersaturated state to promotediffusion into the skin. In some embodiments, systemically effectiveamounts of mast cell stabilizers are achieved with transdermal dosageforms by including skin permeation enhancers in the transdermal dosageforms.

Transdermal formulations used in the methods described herein may employtransdermal delivery devices and transdermal delivery patches and can belipophilic emulsions or buffered, aqueous solutions, dissolved and/ordispersed in a polymer or an adhesive. Such patches may be constructedfor continuous, pulsatile, or on demand delivery of pharmaceuticalagents. Still further, transdermal delivery of mast cell stabilizers canbe accomplished by means of iontophoretic patches, microneedle systems,and the like. Additionally, transdermal patches can provide controlleddelivery of the mast cell stabilizer. The rate of absorption can beslowed by using rate-controlling membranes or by trapping the compoundwithin a polymer matrix or gel. Conversely, absorption enhancers can beused to increase absorption. An absorption enhancer or carrier caninclude absorbable pharmaceutically acceptable solvents to assistpassage through the skin. For example, transdermal devices are in theform of a bandage comprising a backing member, a reservoir containingthe compound optionally with carriers, optionally a rate controllingbarrier to deliver the compound to the skin of the host at a controlledand predetermined rate over a prolonged period of time, and means tosecure the device to the skin. In some embodiments, transdermal deliveryof a mast cell stabilizer, e.g., cromolyn sodium, is provided usingtopical formulations of the mast cell stabilizer, e.g., cromolyn sodium.

Injectable Formulations

Formulations that include a mast cell stabilizer suitable forintramuscular, subcutaneous, or intravenous injection may containphysiologically acceptable sterile aqueous or non-aqueous solutions,dispersions, suspensions or emulsions, and sterile powders forreconstitution into sterile injectable solutions or dispersions.Examples of suitable aqueous and non-aqueous carriers, diluents,solvents, or vehicles including water, ethanol, polyols (propyleneglycol, polyethylene-glycol, glycerol, cremophor and the like), suitablemixtures thereof, vegetable oils (such as olive oil) and injectableorganic esters such as ethyl oleate. Proper fluidity can be maintained,for example, by the use of a coating such as lecithin, by themaintenance of the required particle size in the case of dispersions,and by the use of surfactants. Formulations suitable for subcutaneousinjection may also contain additives such as preserving, wetting,emulsifying, and dispensing agents. Prevention of the growth ofmicroorganisms can be ensured by various antibacterial and antifungalagents, such as parabens, chlorobutanol, phenol, sorbic acid, and thelike. It may also be desirable to include isotonic agents, such assugars, sodium chloride, and the like. Prolonged absorption of theinjectable pharmaceutical form can be brought about by the use of agentsdelaying absorption, such as aluminum monostearate and gelatin.

For intravenous injections, compounds described herein may be formulatedin aqueous solutions, preferably in physiologically compatible bufferssuch as Hank's solution, Ringer's solution, or physiological salinebuffer. For transmucosal administration, penetrants appropriate to thebarrier to be permeated are used in the formulation. Such penetrants aregenerally known in the art. For other parenteral injections, appropriateformulations may include aqueous or nonaqueous solutions, preferablywith physiologically compatible buffers or excipients. Such excipientsare generally known in the art.

Parenteral injections may involve bolus injection or continuousinfusion. Pharmaceutical formulations for parenteral administrationinclude aqueous solutions of the mast cell stabilizers in water-solubleform. Additionally, suspensions of the mast cell stabilizers may beprepared as appropriate oily injection suspensions. Suitable lipophilicsolvents or vehicles include fatty oils such as sesame oil, or syntheticfatty acid esters, such as ethyl oleate or triglycerides, or liposomes.Aqueous injection suspensions may contain substances which increase theviscosity of the suspension, such as sodium carboxymethyl cellulose,sorbitol, or dextran. Optionally, the suspension may also containsuitable stabilizers or agents which increase the solubility of thecompounds to allow for the preparation of highly concentrated solutions.Alternatively, the active ingredient may be in powder form forconstitution with a suitable vehicle, e.g., sterile pyrogen-free water,before use. In some embodiments, parenteral formulations are prepared toprovide sustained release of a mast cell stabilizer. In someembodiments, sustained release is provided by incorporating liposomes,stealth liposomes, bioerodible polymers, and the like into parenteralformulations to maximize the residence time in circulation and/or toincrease absorption of the mast cell stabilizer.

Implantable Formulations

Formulations that include a mast cell stabilizer suitable forimplantation may contain physiologically acceptable sterile aqueous ornon-aqueous solutions, dispersions, suspensions, or emulsions. In someembodiments, the formulations are contained in and delivered from anosmotic pump implant to achieve sustained delivery of the mast cellstabilizer over long durations. In some embodiments, a mast cellstabilizer is formulated with a bioerodible polymer, which, uponadministration facilitates the formation of a depot containing the mastcell stabilizer. The depot would then erode and release the mast cellstabilizer over a duration determined by the composition of thebioerodible polymer. In some embodiments, viscosity modifying agents,stabilizers, and other excipients may be used in the formulation toachieve optimum delivery over an extended duration.

Inhalation Therapy

An “inhalation device,” as used herein, refers to any device that iscapable of administering a drug formulation to the respiratory airwaysof a patient. Inhalation devices include conventional inhalation devicessuch as metered dose inhalers (MDIs), dry powder inhalers (DPIs), jetnebulizers, ultrasonic wave nebulizers, heat vaporizers, and soft mistinhalers. Inhalation devices also include high efficiency nebulizers.Nebulizers, metered dose inhalers, and soft mist inhalers deliverpharmaceuticals by forming an aerosol which includes droplet sizes thatcan easily be inhaled. The aerosol can be used by a patient within thebounds of an inhalation therapy, whereby the mast cell stabilizerreaches the patient's respiratory tract upon inhalation. In someembodiments, the methods disclosed herein comprise administering to apatient a nominal dose of a mast cell stabilizer by an inhalationdevice. In some embodiments of the methods disclosed herein, aninhalation device is not a bronchoscope.

In some embodiments of the methods disclosed herein, administration of acomposition comprising a mast cell stabilizer, e.g., cromolyn sodium, toa patient with an inhalation device, e.g., a high efficiency nebulizer,a dry powder inhaler, a metered dose inhaler, a thermal aerosol inhaler,or an electrohydrodynamic-based solution misting inhaler, is effectivefor the treatment or prophylaxis of a systemic mast cell relateddisorder because both a systemically effective amount of the mast cellstabilizer and a high deposited lung dose of the mast cell stabilizer isachieved in the patient. Thus, in some embodiments of the methodsdisclosed herein, administration of a composition comprising a mast cellstabilizer, e.g., cromolyn sodium, to a patient with an inhalationdevice, e.g., a high efficiency nebulizer, a dry powder inhaler, ametered dose inhaler, a thermal aerosol inhaler, or anelectrohydrodynamic-based solution misting inhaler, is effective for thetreatment or prophylaxis of a systemic mast cell related disorder thatis not believed to be susceptible to treatment or prophylaxis with amast cell stabilizer because both a systemically effective amount of themast cell stabilizer and a high deposited lung dose of the mast cellstabilizer are achieved in the patient. Furthermore, in some embodimentswhere a mast cell stabilizer is administered with an inhalation device,e.g., a high efficiency nebulizer, a dry powder inhaler, a metered doseinhaler, a thermal aerosol inhaler, or an electrohydrodynamic-basedsolution misting inhaler, the methods disclosed herein provide improvedefficacy for the treatment or prophylaxis of a systemic mast cellrelated disorder relative to administration of a systemically effectiveamount of the mast cell stabilizer by a different route ofadministration, e.g., parenterally or orally, because administration ofthe mast cell stabilizer with an inhalation device, e.g., a highefficiency nebulizer, a dry powder inhaler, a metered dose inhaler, athermal aerosol inhaler, or an electrohydrodynamic-based solutionmisting inhaler, provides both a systemically effective amount of themast cell stabilizer and a high deposited lung dose of the mast cellstabilizer in the patient. In some embodiments, a systemically effectiveamount of a mast cell stabilizer is achieved by delivering the mast cellstabilizer in an aerosol generated by a vibrating mesh nebulizer thatproduces droplets with a MMD of 3.0-4.0 μm and a GSD of 1.5-1.8. In someembodiments of the methods disclosed herein, an aerosol is administeredthrough a mouthpiece of a nebulizer using normal tidal breathing.

Characterization of Inhalation Devices

The efficiency of a particular inhalation device can be characterized inmany different ways, including by pharmacokinetic properties, lungdeposition (deposited lung dose), respirable dose (RD), delivered dose(DD), respirable fraction (RF), respirable drug delivery rate (RDDR),volumetric or mass median diameter (VIVID or MMD), mass medianaerodynamic diameter (MMAD) in combination with the geometric standarddeviation (GSD), and total output rate (TOR), among others. The MMAD andGSD can be measured using a cascade impactor as described in UnitedStates Phamacopeia (USP<1601>). The DD can be measured by using breathsimulation apparatus as described in USP<1601>. The RF is derived frommeasuring the amount of drug deposited on the cascade impactor plateswith a particular cut-off particle size, and expressing that as afraction of the total amount deposited on the cascade impactor plates,the induction port and the filter. The RD is calculated by multiplyingthe DD by the RF. The TOR is measured by the difference in weight of thenebulizer before and after completion of nebulization divided by theduration of nebulization. VIVID or MMD can be measured with a standardlaser light scattering apparatus such as the Malvern Spraytec.

Pharmacokinetics is concerned with the uptake, distribution, metabolismand excretion of a drug substance. A pharmacokinetic profile comprisesone or more biological measurements designed to measure the absorption,distribution, metabolism and excretion of a drug substance. One way ofvisualizing a pharmacokinetic profile is by means of a blood plasmaconcentration curve, which is a graph depicting mean active ingredientblood plasma concentration on the Y-axis and time (usually in hours) onthe X-axis. Some pharmacokinetic parameters that may be visualized bymeans of a blood plasma concentration curve include AUC_(last),AUC_((0-∞)), C_(max), T_(1/2), and T_(max). An enhanced pharmacokineticprofile in a patient can be indicated by increased AUC_(last),AUC_((0-∞)), C_(max), or T_(1/2), a decreased T_(max), or an increasedT_(max). Enhanced levels of a mast cell stabilizer in the blood plasmaof a patient may result in better control of or improved symptoms of asystemic mast cell related disorder.

The deposited lung dose may be expressed as a percentage of the nominaldose that is deposited in the lung. For example, a lung deposition of30% means 30% of the nominal dose is deposited in the lung. Likewise, alung deposition of 60% means 60% of the nominal dose is deposited in thelung, and so forth. Lung deposition (deposited lung dose) can bedetermined using methods of scintigraphy or deconvolution.

RF, DD, RD, and RDDR are calculated parameters based on in vitro datathat provide technical dimensions for the efficiency of an inhalationdevice. RF represents the percentage of the delivered aerosol, orinhaled mass, that penetrates into the gas-exchange region of the lungs.RF may be measured with a cascade impactor or laser diffractionapparatus. RF is expressed herein as the percentage of an aerosoldelivered with an inhalation device that has a particular particlediameter or range of particle diameters. For example, the term “RF (≤3.3μm)” as used herein refers to the percentage of an aerosol deliveredwith an inhalation device that has a particle diameter less than orequal to 3.3 μm. Similarly, the terms “RF (1-5 μm)” and “RF (≤5 μm)” asused herein refer to the percentage of an aerosol delivered with aninhalation device that has a particle diameter in the range of 1 μm to 5μm, or less than 5 μm, respectively. DD is the portion or percentage ofthe nominal dose that is actually emitted from the mouthpiece of thedevice. The difference between the nominal dose and the DD is the amountof drug lost primarily as residues, i.e., the amount of drug remainingin the inhalation device after administration or lost in aerosol form.RD is an expression of the delivered mass of drug contained withindroplets or particles having a certain diameter emitted from aninhalation device, such as a DPI, MDI, or nebulizer, that are smallenough to penetrate into the lung of a patient. The RD is determined bymultiplying the DD by the RF. RDDR is the speed at which a respirabledose of the drug is delivered to a patient's lungs. RDDR, measured as afunction of μg or mg/min, is determined by dividing the RD by the amountof time necessary for inhalation. The amount of time necessary forinhalation is measured as the amount of time from the first moment ofadministration of the emitted droplet or powder from the nebulizer, DPI,or MDI until the emitted or delivered droplet or powder of a respirablediameter is delivered to the lung.

Aerosol particle/droplet size is one factor determining the depositionof aerosol drugs in the airways. The distribution of aerosolparticle/droplet size can be expressed in terms of one or more ofVMD/MMAD and GSD. GSD is a dimensionless measure of a droplet sizedistribution curve relevant for characterizing terms such as VMD, MMD,and MMAD. In general, the smaller the GSD for a particular particle sizedistribution, the narrower the distribution curve.

Conventional Inhalation Devices

Conventional inhalation devices may be mechanical or electrical, andinclude, for example, jet nebulizers and ultrasonic nebulizers. Jetnebulizers generally utilize compressors to generate compressed air,which breaks the liquid medication into small breathable droplets, whichform an aerosolized (atomized) mist. In some embodiments, when thepatient breathes in, a valve at the top opens, which then allows airinto the apparatus, thereby speeding up the mist generation; when thepatient breathes out, the top valve closes, thereby slowing down themist generation while simultaneously permitting the patient to breatheout through the opening of a mouthpiece flap. Some nebulizers mayprovide the aerosol in a continuous mode (e.g., the eFlow from PARIPharma Starnberg), by a breath enhanced mode (e.g., the PART LC Plus orSprint from PART Starnberg), by breath actuated mode dependent on thebreathing pattern of the patient (e.g., the AeroEclipse from Trudell,Canada or the I-Neb from Philips Respironics), or according to giveninhalation profile (e.g., the Akita from Activaero, Gmuenden, Germany).

Insome embodiments, a dry powder inhaler used to administer an inhalationformulation in the methods disclosed herein comprises a pre-metereddose, such as Plastiape Monodose inhaler, which comprises a capsulepre-filled with a powder. In some embodiments, a dry powder inhaler usedto administer an inhalation formulation in the methods disclosed hereinhas a device-metered system such as Twisthaler, sold by Schering Plough,which comprises a reservoir to store a powder and a twisting top todispense each dose. Inhalation formulations for administration with adry powder inhaler may be prepared by blending a mast cell stabilizer,e.g., cromolyn sodium, with lactose, or spray drying a mast cellstabilizer, e.g., cromolyn sodium, or by pelletizing a mast cellstabilizer, e.g., cromolyn sodium, to form free-flowing sphericalagglomerates.

In some embodiments of the methods disclosed herein, compositionscomprising mast cell stabilizers are administered with a thermal aerosolinhaler. In some embodiments, the aerosol in a thermal aerosol inhaleris generated by directly heating and vaporizing a thin solid film of themast cell stabilizer, e.g., cromolyn sodium, or by heating andvaporizing a solution of a mast cell stabilizer, e.g., cromolyn sodiumin solvents such as propylene glycol and/or glycerol and water.

In some embodiments of the methods disclosed herein, compositionscomprising mast cell stabilizers are administered with anelectrohydrodynamic-based solution misting inhaler.

High Efficiency Nebulizers

High efficiency nebulizers are inhalation devices that comprise amicro-perforated membrane through which a liquid solution is convertedthrough electrical or mechanical means into aerosol droplets suitablefor inhalation. High efficiency nebulizers can deliver a large fractionof a loaded dose to a patient. In some embodiments, the high efficiencynebulizer also utilizes one or more actively or passively vibratingmicroperforated membranes. In some embodiments, the high efficiencynebulizer contains one or more oscillating membranes. In someembodiments, the high efficiency nebulizer contains a vibrating mesh orplate with multiple apertures and optionally a vibration generator withan aerosol mixing chamber. In some such embodiments, the mixing chamberfunctions to collect (or stage) the aerosol from the aerosol generator.In some embodiments, an inhalation valve is also used to allow an inflowof ambient air into the mixing chamber during an inhalation phase and isclosed to prevent escape of the aerosol from the mixing chamber duringan exhalation phase. In some such embodiments, the exhalation valve isarranged at a mouthpiece which is removably mounted at the mixingchamber and through which the patient inhales the aerosol from themixing chamber. Still yet, in some embodiments, the high efficiencynebulizer contains a pulsating membrane. In some embodiments, the highefficiency nebulizer is continuously operating.

In some embodiments, the high efficiency nebulizer contains a vibratingmicro-perforated membrane of tapered nozzles that generates a plume ofdroplets without the need for compressed gas. In these embodiments, asolution in the micro-perforated membrane nebulizer is in contact with amembrane, the opposite side of which is open to the air. The membrane isperforated by a large number of nozzle orifices of an atomizing head. Anaerosol is created when alternating acoustic pressure in the solution isbuilt up in the vicinity of the membrane causing the fluid on the liquidside of the membrane to be emitted through the nozzles as uniformlysized droplets.

Some embodiments of high efficiency nebulizers use passive nozzlemembranes and a separate piezoelectric transducer that stimulates themembrane. In contrast, some high efficiency nebulizers employ an activenozzle membrane, which use the acoustic pressure in the nebulizer togenerate very fine droplets of solution via the high frequency vibrationof the nozzle membrane.

Some high efficiency nebulizers contain a resonant system. In some suchhigh efficiency nebulizers, the membrane is driven by a frequency forwhich the amplitude of the vibrational movement at the center of themembrane is particularly large, resulting in a focused acoustic pressurein the vicinity of the nozzle; the resonant frequency may be about 100kHz. A flexible mounting is used to keep unwanted loss of vibrationalenergy to the mechanical surroundings of the atomizing head to aminimum. In some embodiments, the vibrating membrane of the highefficiency nebulizer may be made stainless steel, or of anickel-palladium alloy by electroforming.

In some embodiments, a high efficiency nebulizer may be adapted oradaptable to operate in conjunction with a unit dosage form, such as anampule or vial, which contains a single dose of a mast cell stabilizercomposition for the treatment of a systemic mast cell related disorder.The unit dosage form comprises a container that contains an inhalationformulation comprising the mast cell stabilizer, such as cromolynsodium. The container is adapted to cooperate with the high efficiencynebulizer device in such a way as to permit administration of thenominal dose of the inhalation formulation to a patient. In someembodiments, the high efficiency nebulizer and the unit dosage form areconfigured so that they are useable together, but not with other devicesor dosage forms. In some particular embodiments, the unit dosage form isconfigured such that it fits into a keyhole-like structure in the highefficiency nebulizer, but will not operate with other nebulizer devices.In such embodiments, the high efficiency nebulizer is configured suchthat it will accept and properly operate with the unit dosage formcontaining the mast cell stabilizer, but not with other dosage forms.

Secondary: To assess the safety and tolerability of PA-101 in comparisonwith marketed formulations of cromolyn sodium (oral solution and aninhalation aerosol).

Methodology:

This was a Phase 1, randomized, open-label, single-centre, dose-ranging,cross-over study conducted in two parts in total of 18 subjects. Part 1was conducted in total of 12 healthy adult subjects of 18-45 years ofage. Part 2 was conducted in a total of 5 adult patients of 18-45 yearsof age with systemic mastocytosis. Parts 1 and 2 were conducted inparallel.

Study Treatments, Dose and Mode of Administration: Part 1

-   -   1. 40 mg PA-101 (4% DSCG, 40 mg/1 mL), oral inhalation via eFlow        30 L.    -   2. 80 mg PA-101 (4% DSCG, 80 mg/2 mL), oral inhalation via eFlow        30 L.    -   3. 40 mg PA-101 (4% DSCG, 40 mg/1 mL), oral inhalation via eFlow        40 L.    -   4. 20 mg cromolyn sodium inhalation aerosol (1% DSCG, 20 mg/2        mL) (commercially available product), oral inhalation via LC        Plus.    -   5. 200 mg oral sodium cromoglycate solution (commercially        available product), oral administration.

Part 2:

-   -   1. 40 mg PA-101 (4% DSCG 40 mg/1 mL), oral inhalation via eFlow        30 L    -   2. 200 mg oral sodium cromoglycate solution (commercially        available product), oral administration.

In Part 1, all study subjects received each study treatment in themorning (at 8:00 am, +/−30 minutes) as a single dose treatment. Prior toeach dosing day, subjects were admitted to the clinic in the morning forbaseline (pre-dose) assessments. Subjects were required to remain in theclinic for 12 h after study drug administration on each dosing day.Treatment Visits were separated by a washout period of 2 to 5 days.

In Part 2, all study subjects received each study treatment three timesdaily (TID) (at 08:00 am, 14:00 pm and 20:00 pm, +/−30 minutes) as asingle day treatment. Prior to each dosing day, subjects were admittedto the clinic in the morning for baseline (pre-dose) assessments.Subjects were required to remain in the clinic for 24 h after study drugadministration on each dosing day.

The main delivery device for administering PA-101 was the open systemeFlow nebulizer using the 30 L aerosol head, which generates aerosolparticles with a median size of about 3.0 μm. The 40 L aerosol head(generating aerosol particles with a median size of about 4.0 μm) wastested as a comparator arm in Part 1 only.

Duration of Study:

The duration of both Parts 1 and 2 of the study was one day.

Modeling of lung deposition with an aerosol from the 30L and 40L devicesusing the Finlay model (Finlay, W H, and A R Martin, “Recent advances inpredictive understanding respiratory tract deposition”, Journal ofAerosol Medicine, Vol 21:189-205 (2008)) indicated that the lungdeposition with the two devices should be very similar. However, the AUCvalue obtained with 40 mg dose using the 30 L device (338 ng*hr/mL) wassurprisingly high compared to the value (212 ng*hr/mL) from the 40 Ldevice. Cromolyn sodium is not metabolized in the body and is excretedintact via bile and urine. Cromolyn sodium deposited in the lung duringinhalation will appear in the plasma, and the AUC would therefore be asurrogate for cromolyn sodium deposited in the lung. Any cromolyn sodiumswallowed during inhalation will contribute negligibly to the AUC sincethe oral bioavailability of cromolyn is only about 1% (Richards et al, JPharmacol Exp Ther, Vol. 241, No. 3: 1028-1032 (1987)). The AUC datatherefore indicate that at the same dose (40 mg), the lung depositionwith the 30 L device was surprisingly higher than that with the 40 Ldevice.

The numbers of adverse events observed in the single dose study (Part 1)are shown in the following table:

Following the Screening Visit (SV), eligible subjects enter a 4-weekWashout/Baseline Period for daily assessment of baseline symptoms usinga diary and to washout cromolyn sodium in oral cromolyn sodium users. Atthe end of the Washout Period, eligible subjects are randomized toreceive cromolyn sodium inhalation formulation using a high efficiencynebulizer or oral cromolyn sodium formulation or placebo for 6 weeks.

The main criteria for inclusion are: a) Indolent systemic mastocytosispatients uncontrolled with antihistaminic therapy; b) 18-65 years ofage; c) mastocytosis diagnosis confirmed by positive bone marrow biopsy;d) no recent systemic corticosteroid or immunosuppressive therapy; e) nohistory of cancer except basal cell carcinoma; and, f) no concurrentuncontrolled disease.

Criteria for Evaluation:

The primary efficacy variable is significant improvement in clinicalsymptoms at the end of treatment period following treatment withcromolyn sodium inhalation formulation when administered using a highefficiency nebulizer in comparison with oral formulation of cromolynsodium.

The PK parameters evaluated for plasma cromolyn sodium are maximumconcentration (C_(max)), time to maximum concentration (T_(max)),terminal elimination half-life (T_(1/2)), area under the plasmaconcentration-time curve from time=0 to time of last measurable drugconcentration (AUC_(0-t)), and area under the plasma concentration-timecurve from time=0 to infinity (AUC_(0-∞)).

The safety parameters include adverse events (AEs) including assessmentof gastrointestinal disturbance (e.g., abdominal pain, nausea,vomiting), and changes in vital signs and clinical laboratory tests.

Results:

At the end of the treatment period, patients exhibit a significantimprovement in clinical symptoms with minimal AEs as compared to placeboand the oral formulation of cromolyn sodium.
